Handling Critical System Requirements in Adaptive Systems.
Li Na Gong, Teresa F. Lunt · 1995
Abstract : Computer systems implementing mission-critical applications typically must be capable of adapting to and responding to events and changes in the operational environment. To accomplish this, a system often will have to make dynamic tradeoffs in meeting its various and often conflicting objectives: for example, security and availability. In this final report, we describe a general framework within which multiple critical system properties can be specified, multiple requirements can be jointly considered, and conflicts can be resolved. We give examples to illustrate how the framework can be useful, and suggest future work on the application of the framework.
